` fa. citizen of Beit knownthat I, J AMES hinn'rsfiir EARLY,

Goldield, iir the county of Esmeralda and State ofNevada, have invented a new and.

useful Device fp r flapping Cans, `of which the i .followingis afspecificati'on.

This device relates-to can tappers, and is 'i intended for use with canscontaining liquids,

jcans containing cream, '15s ru'p, and th" like.

` tiese v fproductrfe generally sealed, and

- sincebuta port-` i @at atime, it 'has and such other substances that can betaken ering..A -f It is particularly :adapted for use lwith condensed milk,

The cans containing n of theircontents is"used been found that the best results are obtainedby perforating the head. y

i This. method keeps'the'contents cleaner and ina better condition-'than if the' ent'irehead were removed.` Ho\ vever, `the perforating ,metho'd,'fv'sjhile reducing the dangerfof out# side matter entering vthe can, does not by come t iisdefect by providing a device to be form'4 thedoub efunction of p'erforatiig the can with ventfand flow openings, and to automatically close these openings when vthe can is not ,in use, thereby positively preventf ingthe entranceof dust, flies7 ants,', 'like' With these and other objects 1n view, as

or the fully' hereinafter a pear the inven# i tion consistsln-certain nove vfeatures of construction and arrangementof p arts,fherein after fully described., illustrated .in the accom;-

' tiona 'and particularly peinted claims, it being understood that various lchanges in the 'form` proportions, 4size and minor 'details o f the structure may be made without departing from. the is iritor saicrificing lany of the ad-v vantages o the invention. .'In the accompanying drawings :f-Figr11e 1 is a sectional vlew offthe device applied to a milk can, showmg the method of' 'closing the a ertures-in the head. Fig. 2 is a .sec-

view of the same showing the position of the parts when the can isin use 'or the contents about to be removed. Fig. 3 is a.

perspective view of the device.

panying drawings,

the United States',"residingat ployed. to indicate corresponding 'parts -gfhe clamping member 1 is formed preferV vably of a single piece of s rin Wire intermediately bent' to form the lhead 2 andthe remainder extending rearwardly from the head forming parallelsides whicli'lie 'across the vtop right angles an wardly,`forming terminating in a' rest against the head ofthe can diametrically op osite the head' 2. The function of the U- haped handle is to render the device adjlpstable to different diameters of cans. he frame plates 4 and 5 are secured curved downwardly and u a U-shaped handle, the ends lars 6 formed on the lower ends of the plates. The plates 4 and 5 form a frame in which the ter are substantially maul sha e with conical heads' 7 and 8, one 'end of each ead terminating'in a sharp point and iiat on the opposite end. The vhandles 9 of the perforators ex- -jacent their free ends are provided with openends of which are journaled'in alinin openand - A plate are lugs `11- projecting'from the frame' at right angles.v

The armsof the lever embrace the frameand extend parallel 'to rise between the larms of thelever, as shown in Fig. 2. Disposed intermediate the arms ofthellever 12 and secured thereto isa cross bar 1310i a length sufficient to overlie the vshoulders 1() formed 'on the arms 9 of the perforators.` The Afunction of this cam is to rock the perforators on their ivots when the lever is forced downward an raise them from the openingsin the fheadof the-cam -to the osi- Similar numerals of reference are emtion'shown in Fig. 2. On the release o the perforators-are pivotally mounted.

A can attachment comprising clamp! ing frame formed of A spring Wire one end of said frame being bent to form a handle that is l r l l l l l The perforai yieldably held lagainst the side of can, puncturing members carried by the frame, and a lever for actuating said members to openand seal the punctures. A.

5. A can attachment comprising al ieee of spring wire centrally bent to form a oop for vengagement with one side of a can, and a the contents of the ban, the lever .12 isl pressed downward, and the perforators raised, and when the required amount of sub-l stance has iiowed from the can the lever is released and the parts return to their normal position. When the device is applied to a can the handle forms a convenient lmeans by which the can as a Whole may be raised and the contents poured after depressing the thumb piece 12 and opening the vent and v pouring punctures.

I clalmz- 1. A device for forming .vent and low openings in a can embodying a frame, puncture forming members pivotally mounted in said rframe, and means for actuating said members to simultaneously open and seal said fpenings.

2. can attachment comprising a handled'clamping frame arranged to engage the top of the can, puncturing members mounted in said frame and arranged to form vent and How o enin s inthe can, and a thumb lever carrie by t e frame and ada ted to actuate said members to open andsea said openings.

3. A device for forming vent and flow openings in a can embodying a frame, puncture forming members plvotally mounted in said frame a lever pivotally connected to said frame and provided With a mea-ns for actuatpair of parallel bars to extend across the top of the can, the wire being thence bent into approximately U-form to form a handle' that is yieldably held against the opposite side of the can, puncturing members` carried by the frame, and a lever for actuating said puncturing members'. c l

6.v Inra device for formingvent and flow perforations in a can, a clamping device supporting a frame, a pair ofperforating members independently mounted in said frame, a.

lever having a means thereon for simultaneously tripping the members.

v7'. In a device for forming vent andrlow perforations in a can, al1-adjustable clam ing member adapted to fit over the head o the can supporting a pair of frame plates se-,

cured thereto, a pair of independently mounted perforators mounted on pivots in said frame, a bifurcated lever secured to the frame and a cross bar carried .by said vlever adapted to simultaneously rock the. perforating members on their plvots.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.
